Halo 5 won't work on my brothers console

So recently my brothers downloaded Halo 5 because it is free and this morning it said he had to sign into a different Xbox account to play, but he downloaded it off of the one he normally uses (which is not mine). So my question is: Do you have to pay for halo 5 after the week is over? Or is something wrong with our Xbox?

The Halo 5 free-to-play promotion ended on July 6; if you want to continue to play Halo 5, you’ll have to pay for it.

Ok thanks man. That sucks :frowning:
